Hi,

You may not have all the dependencies installed on your system to build GTK+ from source. Make sure that you have all development dependencies installed so that you can compile the sources.

You may find it easier to install GTK+ from a pre-built and packaged bundle. This will usually be a .rpm or .deb and will vary depending on which system you are using. You will normally have a package manage that can install it for you.

XInput version 2 is a dependency starting with gtk+-3.4.0. So I'll assume your trying to install at least gtk+-3.4.0.
The file called: "INSTALL" contains the list of dependencies. For instance gtk+-3.4.3 (newest stable version) has:

Prerequisites
=============

GTK+ requires the following packages:

- The GLib, Pango, GdkPixbuf, ATK and cairo libraries, available at
the same location as GTK+. GTK+ 3.4.3 requires at least
GLib 2.32.0, Pango 1.30.0,
GdkPixbuf 2.26.0, ATK 2.2.0
and cairo 1.10.0.

- Each GDK backend has its own backend-specific requirements. For
the X11 backend, X11 R6 and XInput version 2 (as well as a number
of other extensions) are required.

- gobject-introspection 1.32.0 or newer.

You can download the source to check the "INSTALL" file from here and just change the 3.4 to whatever series you're using: http://ftp.gnome.org/pub/gnome/sources/gtk+/3.4/
I could advise you better if you listed what your O.S. and revision is but I just posted a rather extensive step-by-step for installation here:
